Opinion | Why Would a Republican Vote Biden? Ask Arizonans – The New York Times

Why is Arizona suddenly a swing state?

The answer is frequently attributed to changes in the demographics of our electorate. It is true that Arizona’s population is increasingly urban, college-educated and Latino — trends that favor the Democratic Party.

But this influx of Democratic-leaning groups doesn’t explain the change. After all, the proportions of registered Republicans and Democrats in Arizona have remained remarkably stable: Registered Republicans solidly outnumber registered Democrats.

What has changed is that more Republicans aren’t voting for the party’s candidate in elections for national office.
